Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1; The operation principle of the solar cell panel assembly of the utility model is: on four edges, the four corners of the world at the back side of cell panel, a photoelectric sensor (being respectively V1, V2, V3, V4) is housed respectively; Photoelectric sensor is connected to the input of CPU; The output of CPU also is connected with the drive circuit of V1, V2, V3, V4, and each drive circuit is connected with stepping motor respectively, and may command cell panel southwest eastwards is northern to rotation.Can not sense sunlight when certain photoelectric sensor wherein, be equivalent to open circuit like this between the collector electrode of photoelectric sensor and the emitter, four I/O mouths of CPU all are low level; If when the sun at a time makes one of them photoelectric sensor conducting; So just explain that this photoelectric sensor exposes in the sun; Solar panel does not face the sun; CPU according to the state of detected four I/O mouths confirm operation east, south, west, northern to stepping motor, all be low level in case detect four I/O mouths, then stop the operation of stepping motor.
We know that the irradiation of sunlight angle is different along with the difference of time.If solar panel is fixed on certain angle, along with the variation of sun irradiation angle, cell panel can't remain vertical with sunlight, makes conversion efficiency on the low side.Shortcoming to this fixed form cell panel; We utilize the relation property of photoelectric sensor output level and light intensity, the variation of angle between sunray and the plate face are changed into the variation of electrical quantities, through logical operation; Convert the anglec of rotation output of motor into; Drive motor is made respective reaction, guarantees that cell panel plate face is vertical with light all the time, reaches the peak use rate of sunlight.
Referring to Fig. 2-4; From the solar cell panel assembly of motion tracking sunlight by solar panel 1, support 4, rotating mechanism 3, the photoelectric sensor (installation site of label 2,21,22 expression photoelectric sensors among Fig. 2; Among Fig. 4, the installation site of label 2,21,22,23,24 expression photoelectric sensors), drive motors, drive circuit form, wherein; Drive motors is included in four stepping motors that the cell panel below is provided with by four corners of the world direction; Be provided with the whirligig that is connected with four step motor shafts respectively in the rotating mechanism 3, to the step motor control that is provided with, cell panel 1 rotated on all directions by east, south, west, the north.Be placed on the fixed base for solar panel 1 is stabilized in, on support 4, be provided with three drag-lines 5, an end of drag-line 5 connects fixed base 6.Support 4 is provided with the cable-through hole 41 of power supply for step-by-step motor line, photoelectric sensor power line.
Be provided with photoelectric sensor V5, east, south, west, north in the front center position of solar panel 1 and on four limits four photoelectric sensors be set, be respectively V1, V2, V3, V4 in Solar panel backside.When sunlight was arranged, the photoelectric sensor in the front of solar panel output high level was to CPU, but each drive circuit of CPU control this moment is an operating state.When cell panel 1 faced sunlight work, four photoelectric sensors of Solar panel backside were not exposed under the sunlight, and then all output low level is to CPU, and this moment, stepping motor was not worked.When the change of sunlight direct projection direction, cell panel do not face sunlight work; The corresponding light electric transducer at the cell panel back side is then exported high level to CPU; CPU then controls corresponding stepping motor work, and after regulating cell plate to the sunlight direct projection direction, stepping motor quits work.
When cloudy day or evening; The photoelectric sensor output low level of the front center position of solar panel is to CPU; This moment, CPU control step motor was an off position, had avoided the problem of cell panel loss electric energy when not shining upon, and had reduced the loss of electric energy effectively.We are defined as 1 with the high level output of photoelectric sensor, and low level output is defined as 0, and then the driving rule of each stepping motor sees table:
If certain angle is arranged between sunlight and the solar panel, so necessarily there is wherein one or two to be exposed under the sunlight, photoelectric sensor is not when being exposed under the sunlight; The equal output low level of V1～V4 " 0 "; In case four merely hit one or two be exposed under the sunlight, make it to be in conducting state according to the characteristic of photoelectric sensor, because the collector resistance of photoelectric sensor is smaller; Has only 1/10 of emitter resistance; So it exports high level " 1 ", in a single day CPU has detected this signal, and CPU comes the drive stepping motor operation with regard to control Driver Circuit.Such as: photoelectric sensor in the east is exposed under the sunlight; CPU drives stepping motor in the east with regard to control Driver Circuit 1; Make stepping motor by clockwise or rotation counterclockwise, make it to be exposed to photoelectric sensor sunlight under and be output as low level and just stop to move.In like manner; If there are two to be exposed under the sunlight simultaneously; Such as east, south to photoelectric sensor be exposed to simultaneously under the sunlight, regulate stepping motor in the east so earlier, make photoelectric sensor in the east be output as low level; And then the stepping motor in adjusting south, make the photoelectric sensor in south be output as low level.So just reached solar panel directly to sun direction of light, made solar panel maximally utilise the luminous energy of the sun.
The effect of the photoelectric sensor V5 of the front center of solar panel is to be used for differentiating to be daytime or evening, fine day or cloudy day; So if V5 output is low level; Explain that then sunray is weak even do not have sunlight; Then all stepping motors are failure to actuate, and avoid the stepping motor misoperation, prolong the useful life of stepping motor.
Yan Dong, face, west, the north are to being symmetrically arranged with guide rail at the back side of solar panel.Be provided with suitable slide block in the guide rail, therefore photoelectric sensor is fixed on the slide block; Photoelectric sensor is any adjusting position in the process that reality is used; When wanting to let photoelectric sensor earlier experience sunlight, can move to photoelectric sensor by the cell panel edge, if want to let photoelectric sensor experience sunlight a little later; Just can lean on photoelectric sensor a bit toward the center; Can reduce the frequent movement of stepping motor like this, when having only the angle that becomes with solar panel when sunlight bigger, just need the stepping motor action.
